The remarkable little water-plant upon which this gemis is founded is a native of
the United Slates of North America and Canada, and was found early in the present
century by Mr. Brown in Australia, and latterly by GrilUth in the Khasia Mountains
and Bhotan. Jttaiug inconfqucuouB, it is probably not HO rare as is supposed to be the
case. We are quite unttbln to detect any difference between our specimens which we
have preserved in apirits, and tlio excellent analysis in Gray's l Genera of United
States Plants/ except that the iilnmeuts and donnm of the sepals arc puberulous.
Asa Gray observes that the curious mucilaginous covering of the peduncles and pe-
tioles is formed by the rapid formation and rupturing of nuceeasive epithelial cells, as
mucilage is formed on the surfaces of nniinal mucous incuibranea ; we may observe that
the gelatmoua coat of 4he stieds of various Contpositte and Gruelftrtf is ({«;t<! analo-
gous. Gray further states that (he vhizoma contains obloug truiun cicely auuidutcd
